What Battery Did You Really Buy?

From my learning I am beginning to understand that battery re-wrappers need to be better scrutinized. How sure can we be that the labeled battery is what is printed on the re-wrapp?

Below is a link I found quite interesting; the reviewer too made a complementary comment about HJK as well.

His review is for AWT IMR 18650 3000mAh 40 amp.
